The reason that you are getting these vertical lines on your screen is bcause your horizontal output chip is bad. If you have electronic experience please replace it. If you do not please dont attempt to do this call a tech because you can end up doing more damage to your TV

I have a sharp 32av22u which has vertical lines and at moments i get a picture and sound and then lines appear and screen fades to multi color but still have sound


Hi,
This is a problem with the LCD's inverter cable, the cable that connects the LCD to the mainboard. Have it checked, reseated or replaced by a certified technician to prevent damage of other parts.

Sharp lc-32sh12u...no picture


It can be either the LCD panel driver board, or the worst case is bad LCD panel.

Sharp tv model lc-26sh12u very low vulumn even at max volumn control


Yes, don't buy SHARP, problem solved! SHARP is the worst brand of LCD TV. I had to bring my brand new SHARP TV in for repair within 8 months of buying it brand new, and of course it was no longer under the 90 day labor warranty. Also, every person I know who has a SHARP TV has issues with volume and eventually end up with a black vertical line along the side of the screen within 1 to 2 years. I highly reccomend SONY, PANASONIC, even SAMSUNG, LG or VIZIO. Heck, I'd go with Toshiba or Phillips before I'd ever buy anything SHARP again I was so annoyed with their customer service.

What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.

Vertical line


Sorry, you have a defective LCD panel. If your TV is still under warranty, contact Sharp to get the TV exchanged. Otherwise, LCD panels cost more than the TV is worth.
